Step 3: Select the customer value column for your Custom Audience

Important! In order for Facebook to understand the data in your uploaded customer file, follow all the best practices explained in this guide by Facebook, including:

Include a full range of customers, from low to high value. This way, Facebook’s algorithms get more data to differentiate good customers from bad ones

Use dollar values only and avoid using other numeric values such as rankings or ratings

Don’t use negative values to signify undesirable customers as Facebook won’t count those

Use a single currency throughout your columns to avoid any confusion about your data

Once you’ve selected the customer value column and everything’s looking good, save the new Custom Audience.
